AIR CONDITIONER Filed April 9, 1936 ATTOMEY v Patented June 1, 1937 AIR CONDITIONER James Lovely, San Jose, Calif., assignor of onehalf to Luther Rice, San Jose, Calif.

Application April 9,

2 Claims.

The present invention relates particularly to means for cooling the air in a closed car.

It is common knowledge that the occupants of a closed car suffer greatly from the heat during warm weather, and particularly when driving through arid or semiarid country such as our desert regions of the West. Under conditions existing at such times the mere forced circulation of the air, as with a fan, does not give any material relief.

It is, therefore, one object of my invention to provide means for lowering the temperature of the air in a car as well as to set up a forced circulation of the same.

It is another object of the invention to provide means of the character indicated that may be mounted inconspicuously within the car body and that will occupy but little space therein.

It is still another object to provide means of the character indicated that may be readily and easily serviced.

It is also an object to provide means of the character indicated that will be economical to manufacture, simple in form and construction,

compact in form, economical to operate, and

highly eflicient in its practical application,

In the drawing:

Figure 1 is an elevation of a device embodying my invention, partly in section and having parts broken away.

Figure 2 is an end view of the same.

Figure 3 is a front elevation of the same. v

In the particular embodiment of the invention herein disclosed, I show at i a plate mountable in any suitable manner and in any desirable location in the car.

At 2 I show an end plate mountable on plate I as at 3 and provided with a peripheral flange l to form a seat for the body of the device hereinafter described. This plate is circular in form but has a projecting front portion as shown at 5. Concentric with the axis of the plate is another circular flange 6, this flange forming a seat for one end of the container of the cooling medium as hereinafter described.

At 1 is shown another plate substantially identical with plate 2 and mounted in opposed relat on thereto, the corresponding parts being indicated at 8, 9 and ill respectively. This plate,

however, has an opening II formed therein, and a seat at I2 to receive a closure I 3, the closure being secured in position by fingers l4 pivotally mounted at I5.

At I6 is shown a cylinder seated in the two flanges 4 and 8 and having the same form in cross- 1936, Serial No. 73,451

section as the plates 2 and i. The front of the cylinder has two spaced openings formed therein as at I! and i8.

At I9 is shown a cylinder forming a container for solidified carbon dioxide, or dry ice, 2U, thiscylinder having an open end abutting end plate 2 and being held centrally in the chamber 2! by the flanges 6 and 10, its seat in flange 6 being loose enough to permit a small quantity of air to flow thereover. I

Mounted in the cylinder it to extend from end to end thereof is a bafiie 22, this baffle also extending from the front inwardly to the central container I9 and crossing from one side of opening H to the opposite side of opening i8 so that a current of air entering the chamber 2| through opening ll can only escape through opening l8 by passing entirely around the cylinder l9.

At 23 I show a vertically disposed bar mounted as at 24 on the plates 2 and l and placed just back of the openings l1 and i8. This bar supports a fan 25 in axial relation to'opening H, the fan being operated from the battery of the car by suitable electrical connections thereto shown in part at 26.

When the device is in place and ready for use the fan is set in motion, thereby causing a stream of heated air from the interior of the car to enter the chamber 2|. This forced induction of the air into the chamber 2| causes it to circulate around the chamber and the container [9 therein where it gives up some of its heat to the cooling medium and is returned to the interior'of the car through opening l8.

It is clear that a device of this kind will not be operative without recharging over a very long period of time, and that the difference in temperature obtained through the use of the device will not be great, but it is designed for use only when the temperature is excessively high in a car when it will reduce it sufiiciently to make it bearable.

It is desirable that as much heated air as possible be brought into contact with the cooling medium, and this result may be attained in any suitable manner. By providing the long and cylindrical air chamber 2| a turbulence of the air current is secured that satisfactorily accomplishes this result due to the fact that the air current is forced to travel in a circuitous path. The turbulence of the air in chamber 2! may be increased by inserting suitable baflles as at 21, and the cooling of the air may be accelerated by the use of suitable vanes as indicated at 28.

It will be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes in form,

construction, and method of assembly and operation may be made within the scope of the appended claims.

I claim:

1. An air conditioner comprising, a cylindrical housing having air inlet and discharge passages formed therein at opposite ends thereof, air circulating means associated with one passage, a container for solidified carbon dioxide removably supported within the housing in spaced relation to its walls to form a cylindrical chamber therebetween, a passage connecting the interior of the container with said chamber, and means inserted between the housing and container to direct the circulated air in a circuitous path about the container from the inlet to the discharge passage.

2. An air conditioner comprising, a cylindrical to the walls of the housing to form a cylindrical chamber therebetween and communicating with said chamber at its open end, and means inserted between the housing and container to direct the circulated air in a circuitous path of travel about the container from the inlet to the discharge pasv15 sage.
